What is Ecclesiology? Christian Theology

Ecclesiology is the study of the Christian Church. The term is derived from the Greek words ekklesia (assembly or church) and logos (word or study).

 

Nature of the Church 

1. Visible vs. Invisible

Visible: The earthly institution we see—buildings, leaders, and members. It includes everyone physically present in the organization.

Invisible: The spiritual reality known only to God—all true believers across history and the world, regardless of their location or denomination.

2. Local vs. Universal

Local: A specific congregation meeting in a certain place.

Universal: The entire global body of believers. Every local group is seen as a complete representation of the whole universal church.

3. Organism vs. Institution

Organism: A living, growing entity where members are interconnected like parts of a body. It focuses on relationships and spiritual life.

Institution: A formal society with rules and structure. It focuses on order, stability, and carrying out organized missions.

The Structure and Governance

1. Episcopal: Governed by bishops (e.g., Roman Catholic, Orthodox, Anglican).

2. Presbyterian: Governed by elders or representative assemblies.

3. Congregational: Each local church is autonomous and self-governing.

Two Approaches 

1. From Above: This starts with divine revelation and the spiritual identity of the church as a mystical reality created by God.

2. From Below: This focuses on the human reality of the church, looking at its social history, cultural impact, and the actual behavior of its members in the world.

The Marks of the Church
